I was going to buy BRS solutions to maintain the levels in the tank but I need to "quickly" raise the magnesium to where it should be first. Is there a better/cheaper option than to use a bunch of the BRS stuff? I know there are homemade recipes for Calcium and Alkalinity but I've never heard of one for Magnesium. Is there a specific product that's better than another? lastly, how quickly can you raise magnesium without adversely affecting other things? ------------- Jared Page Highland, UT Graphic Designer |

| If there is corals in the tank you shouldn't raise it more than 100 ppm a day and as far as cheaper no there isn't a cheaper way than brs two part at least to my knowledge. |

well, the readings were around 960 if I remember right but to be honest, i don't entirely trust the test kit. It's many, many years old. I've already ordered new test kits so I won't do anything till it arrives and I've re-tested but I just want to be prepared to have whatever I need on-hand as it will take another several days of waiting if I order BRS. Plus, I still have lots of old B-Ionic 2 part solution of Calcium and Alkalinity that I'd like to use up before I get the BRS. ------------- Jared Page Highland, UT Graphic Designer |

Jared -
What is your current reading for Mg? You should be looking to keep it at about 1300 -1400ppm.
If it is under 1000 ppm, I would say you could raise it 200ppm per day until it gets to 1000ppm. After that, go 100 ppm per day until you hit 1400ppm.
'Homemade' Mg mix is simply Epsom Salts (Mg SO4) mixed with Mg Cl... You can use the Epsom Salts by themselves to raise the Mg up to where you want it; however, you should use the mix of both long - term to avoid leaving excess sulfates in your water.

I agree with Bob. In a pinch, you can use epsom salts from the pharmacy or grocery store, but you should combine it with magnesium chloride as soon as possible. ------------- www.reefdup.com Diving since 2009, reefkeeping since 2007, & fishkeeping since 1987 200g, 75g, & 15g Systems PADI Advanced Open Water |

BRS two part is pretty much as cheap as it gets. Sorry. ------------- www.reefdup.com Diving since 2009, reefkeeping since 2007, & fishkeeping since 1987 200g, 75g, & 15g Systems PADI Advanced Open Water |

| Costco sells magnesium chloride for driveway salt. I have some I use for driveway salt if you need some quick. I also use brs mix |

I use the same stuff. I suggest straining it through a coffee filter before putting it in your tank. I tend to get a little black precipitation on the bottom when I first mix it. I also pick up a box of Epsom salts from Costco too. ------------- 40 gal w/ 20 sump |

My new test kit finally arrived and it turns out that the Mg is around 1400. I guess expired kits really don't work. My Alk is really low though so now I'm working that out. ------------- Jared Page Highland, UT Graphic Designer |

Here is a link to help with dosing. The nice thing about this link is that it gives you the option to use DIY solutions such as Epsom and Baking Soda if you want to. It will also warn your dosing will alter your PH. I just raised my Mag with Epsom from 1200 up to 1300 a couple days ago. http://reef.diesyst.com/chemcalc/chemcalc.http://reef.diesyst.com/chemcalc/chemcalc.html |
